Mixed-Metals Codeposition as a Novel Method for the Preparation of LiMn[sub 2]O[sub 4] Electrodes with Reduced Capacity Fades

Mixed-metals codeposition was introduced as an efficient method for the deposition of cathode materials onto substrate surfaces. The approach proposed was typically used for the deposition of LiMn 2 O 4 with codeposition of mixed gold-cobalt. The results obtained for the system under investigation showed that the method employed is applicable for lithium secondary battery performance. In addition to the efficient deposition of the cathode material which is of interest for battery applications, the approach was used to incorporate cobalt oxide into the cathode material. It was demonstrated that the metal oxide deposited with the cathode material significantly reduces the capacity fade of LiMn 2 O 4 in both room and elevated temperatures.
